A 25-mm diameter shaft is pulled through a cylindrical bearing as shown in Fig. 1. The lubricant that fills the 0.2-mm gap between the shaft and bearing is an oil having a kinematic viscosity of 8.0 x 10-4 m²/s and a specific gravity of 0.91. Determine the force P required to pull the shaft at a velocity of 3 m/s. Assume the velocity distribution in the gap is linear.
